During instrument analysis, the flow rate was 0.4ml/min and measurements were made at 65 degrees Celsius.
- the degree of proteinase K degradation over time decreased in the block polymer conjugate containing antibody-linker-polypropylene oxide compared to the existing antibody. It was determined that the decomposition action of the antibody was inhibited by the ‘Steric hindrance’ effect, which physically blocks the access of degrading enzymes by conjugating a block polymer containing polypropylene oxide to the antibody. Through this, it can be expected that the block polymer conjugate containing antibody-linker-polypropylene oxide will have higher in vivo stability than existing antibodies.
- L929 a mouse fibroblast cell line.
- L929 was cultured in RPMI medium containing 10% FBS and 1% penicillin-streptomycin. The experiment was conducted by adjusting the number of cells to 1 ⁇ 104 cells in a 96-well plate. Afterwards, each cell group was treated at a protein concentration of up to 100 ⁇ g/ml. After culturing at 37°C and 5% CO2 for 24 hours, the culture medium was removed, washed once with Dulbecco's phosphate-buffered saline (DPBS), and MTT assay was performed.
- DPBS Dulbecco's phosphate-buffered saline
- the cell line used was the HaCaT cell line, a human keratinocyte, and cultured in DMEM with 10% FBS and 1% penicillin-streptomycin. The experiment was conducted with cells adjusted to 5 ⁇ 104 cells in a 6 well plate. To induce cell apoptosis, recombinant human TNF- ⁇ and cycloheximide (CHX) were used.
- the experiment consisted of a negative control group (SF) that was not treated with TNF- ⁇ and CHX, a positive control group (TNF+CHX) treated with both TNF- ⁇ and CHX, and a positive control group treated with existing antibodies (ADA, IFX, GOL), a positive control group, and a group treated with a block polymer conjugate containing antibody-linker-polypropylene oxide (ADA-PX, IFX-PX, GOL-PX) were divided into a total of 4 groups. Each antibody and the antibody-linker-polypropylene oxide-containing block polymer conjugate were quantified through BCA assay and treated to each cell group at a concentration of 1 ⁇ g/ml based on protein.
- TNF- ⁇ For TNF- ⁇ , it was treated at 50ng/mL, and for CHX, it was treated at 5 ⁇ g/mL. After culturing at 37°C and 5% CO2 for 24 hours, AnnexinV-PI staining was performed to confirm the degree of apoptosis. The cells from each group were treated with media and trypsin-EDTA at the time of culture, and the detached cells were centrifuged (2000 rpm, 5 minutes), and the cells were washed using DPBS (5% FBS).
- each group was treated with AnnexinV-FITC and PI reagents according to the instructions of the AnnexinV-PI staining kit (Abcam, ab14085), and flow cytometry was performed using a flow cytometer (Becton Dickinson Sciences, FACS Canto II).
- a collagen-induced arthritis (CIA) model using DBA/1J species was created.
- 100 ⁇ l of an emulsion mixed with Collagen type-II and complete Freund's adjuvant at a 1:1 volume ratio was administered to the tail to create a CIA model.
- 100 ⁇ l of an emulsion mixed with collagen type-II and incomplete Freund's adjuvant at a 1:1 volume ratio was administered to the tail to induce inflammation.
- the sample was administered by intraperitoneal injection at a dose of 10 mg/kg at the time when the model was judged to have been induced on average.
- the thickness and swelling of the soles and ankles were checked once every three days, and body weight was measured to confirm weight loss due to inflammation.
- the thickness of the sole and ankle were measured at the same location with a vernier caliper.
- scores were evaluated based on the number of edema formed in the toes and ankle edema. An individual without edema receives 0 points, if edema occurs in 1-2 toes, 1 point, if edema occurs in 3-4 toes, 2 points, if edema occurs in all toes, 3 points, if edema occurs in all toes, 3 points.
- leg tissues were collected and H&E staining to check the level of inflammation, Safranin O staining to check cartilage damage, and micro-CT imaging images to check the level of bone erosion.
- Enzyme-linked immunosorbent assay (ELISA) analysis was performed to confirm the expression levels of inflammatory factors through TNF- ⁇ neutralization.
- serum was collected from the blood of mice in the last week of the experiment and ELISA analysis was performed, and the expression level of interleukin-1 ⁇ (IL-1 ⁇ ), an inflammatory cytokine, was confirmed.
- IL-1 ⁇ interleukin-1 ⁇
- All ELISA kits were from abcam, and the analysis process was carried out according to the instructions of the kit.
